The entire SHENFENG production process of the multilayer pipe undergoes continuous quality controls. The below paragraphs illustrate some of the tests applied to pex al pex and pex pipe
The operation is to measure the diameters and the thickness of the individual layers.It is also enables the weld cross-section to be checked and therefore to verify that the pex al pex pipe weld has been correctly carried out.
2,Disruption test (Ring test):
Cut approx. 1cm of pex al pipe, fix it onto the machine and start tearing / pulling it from both sides, up to the moment when the pipe ring is broken. Then check at which point the pipe was broken.This is to test the resistance of the AL overlap welding place.
3,Delamination test (Peel test):
Cut approx. 1cm of pipe, using a computerised dynamometer capable of assessing the force required to separate the aluminium layer from the internal pipe. The test provides a graph describing the value of the force to be applied to separated the layers.
The tests are designed to ensure the product is suitable for sale and to evaluate its hydraulic,mechanical and structral characteristics.
